Pros:
multiple classes, special abilities, ways of attacking the game
very very fast game, maps are just the right size
bombs & all kinds of destruction
solid game modes (TDM, CTF, King of the Hill)
PC, Mac, Linux — very low requirements
exploding shit all over screen, body parts like crazyyy

Cons:
sometimes unclear what’s going on
rounds are very very short
single player isn’t significant, not really point of game though
